Application filed April 13, 1898.

To (LZZ 2 071.011? it may concern: Be it known that 1, WILLIAM H. PAGE,a citizen of the United States, residing at Norwich, New London county,Connecticut, have invented certain new and useful Improvements inHot-Water Heaters, of which the following is'a full, clear, and exactdescription. 7 My invention relates to hot-water heaters, andparticularly that class made up of a multiple of vertical sections, eachof which is suitably'formed to provide water chambers and passages, allof said sections being so connected that free and rapid circulation ofthe water may be maintained. 7

My object is to improve the sections of this class of heaters and alsoto produce a duplex form of heater specially adapted for differenttemperatures. In. carrying this last-named feature of my invention intoeffect I provide in a single structure a heater'of small capacity foruse in moderate weather, a somewhat larger heater for use in'colder'weather, and also a heater of. the combined capacity of the two alreadyspecified for use in extremely cold weather. These heaters differ incapacity, it being possible, as above stated, to operate the sameindependently or in unison, a great range of capacity for the completedevice be-. ing thus made possible.

A further object of my invention is to provide a heater having not onlythe advantages above set forth, but also certain construction wherebythe water is presented to thefire in a most advantageous manner, thislast-named result being accomplished by means of the peculiarconstruction of the sections comprising the heater, all of which ishereinafterfully set forth in detail.

The elementary sections of which my heater is constructed are of threekindsviz., the end sections, of which one is placed at each end of thecomplete structure to formthe front of each of the minor heaters, theintermediate sections, several of which are placed between I said endsections,a11d also what I term the division-section, which forms a backcommon to the two minor heaters-and, as'its name implies, provides adivision-wall between them.

To assist in the explanation of my invenvent-ion, I'have provided theaccompanying drawings, illustrating the same, as follows:

- shown in Fig. 2 of the drawings.

Fig. 2 is a horizontal view of said heater,taken on line 00 a; of Fig. 1, this view showing also, in dotted lines,the outlineof the ash-pit. Fig. 3 is a'horizontal sectional view of thecentral portion of my heater, taken on line y y of said Fig. 1. Fig. 4shows in elevation one of the end sections of my heater. Fig. 5 is asimilar view of the reverse side of the lower portion of said section.Fig. 6 shows in elevation oneof the intermediate sections. Fig. 7 is asectional view of the lower portion of said intermediate section. Fig.8is an edge view of'said end and intermediate sections, said viewbeingcommon to Figs. sand 6. Fig. 9 is an elevation of what I term thedivisionsection. Figs. 10 and ll are edge views of said last-namedsection, taken from the opposite sides of Fig. 9. Fig. 12 is a sectionalView of the lower portion of the division-section. Fig. 13 is asectionalview of the upper portions of said end, intermediate, anddivision sections.

scribe the intermediate section of myheater, calling particularattention to Figs. 6, 7, and v 8, illustrating the same in detail. Thissection, as well as the end and division sections, is hollow, consistingof thin metallic walls, between which the water is confined while beingheated. The upper portion 10 of the said intermediate section is ofcircular form, as shown in elevation in Fig. 6, and depending fromopposite sides thereof are water-legs 11 and 12, that are shaped incross-section as When the heater is assembled,-the water-legs 11 and 12form the side walls of the fire-pot and combustion-chamber. Centrallylocated inthe portion 10 and extending through the same is a circularopening 13, and concentric therewith both' faces of the intermediatesection are recessed to form circular depressions 14, leading frombetween legs 11 and 12 upward to. a point above the circular opening 13,at which point the circular wall l0',inclosin g said opening, is cutaway or stopped off in the casting, as at 14:, providing communicationbetween circular depressions 14 and the open- Referring now tothedrawingsJ will first deencircles the central opening 13.

ing 13. Crossing centrally the circular opening 13, preferably at rightangles to each other and at angles of about forty-five degrees to thevertical center of the com plete heater are two Waterways 15, ofapproximately the same thickness as that portion of the section betweenthe depressions 14.

The lower extremities of the legs 11 and 12 are connected by means ofextensions 1112, leading downward and inward to and connecting withacircular chamber 16 in the line of the vertical center of the section.(See Figs. 0 and S.) The upper portion of each intermediate section hasformed thereon a similar chamber 17, preferably of the same thickness asthe section proper.

Located above chamber 16 is a boss 16, that is bored, as at 16*, toreceive a bolt by means of which the several sections of the heater aretied together, as hereinafter explained, and crossing said intermediatesection at a point below chamber 17 is a boss 17, that is similarlybored, as at 17, to receive a tie-bolt extending through the entire lineof sections.

Formed on the extensions 11 12 of legs 11 and 12 are webs 18, the upperedges of which conform in outline to the shape of the gratesegments, inwhich webs bearings 18 are provided to receive the grate-bar journals.

Reference-number 19 denotes downwardlyextending plates formed on theconfronting inner faces of the legs 11 and 12, which plates serve toguide the fuel to the grate, and thereby prevent its lodgment on thesides thereof. The end section of my heater which forms the front orouter sections of the said minor heaters is shown in detail in Figs. 4,5, and 8. Said section in outline and general construction is the sameas the intermediate section just described, and all points ofcorrespondence are similarly lettered. In order that said section mayserve as the front wall for the firepot, the portions thereofcorresponding tothe legs 11 and 12 of the intermediate section areconnected by a hollow wall 20, which latter also extends upward and Thefront face of wall 20 is preferably depressed, but to a less extent thanthe depressions 14 of the intermediate section; but the rear face ofsaid wall is depressed considerably more than said depressions 14,thereby leaving the thickness of wall 20 approximately half that of thesection as shown in Fig. 1. An opening 21 is provided in wall 20,through which the fire-pot may be reached, and in the opening 13, abovereferred to, the transverse waterways 15 may be omitted in order thatfree access may be had to the upper interior portion of the heater whennecessary to clean the same.

The so-called division -section of my heateris illustrated in detail byFigs. 2, 3, 9, 10, 11, and 12 of the drawings, section in the main islike that of the intermediate and end sections already described, andallpointsof correspondence are similarly numbered. The saiddivision-section is pref- The outline of this erably of somewhat greaterthickness than the end and intermediate sections, and the portions 11and 12, corresponding to the legs 11 and 12 of the intermediate section,are connected by walls 22, of plate form, whose opposite .faces aresomewhat depressed. The circular opening 13 is provided in this section;but one side thereof is cutout, asat 23, through the portion 10 to thecircumference thereof. Thewall 22 extends upward and partly encirclesopening 13, thus forming on each face of the division-section adepression 14:, which enters the opening 23 at 23", at which point theencircling wall 10' of opening 13 is cutaway to allow communicationbetween depression lat and said opening. The lower wall of the opening23 is a continuation of the circular wall 10 of opening 13 and isdenoted by reference-number 10.

Located in the circular opening 13 is an an gular deflector-plate whosefaces are denoted by the reference-numbers 2 1 24'. (See Figs. 3 and 9of the drawings.) The said faces 24 24 of the deflector-plate extendfrom the circumferential wall 10 of opening 13 to a pointapproximatelyin line with the vertical center of said opening, at whichpoint said faces 24 24 meet, forming an acute angle, as shown in theFig. 3.

Located on that edge of the division-section opposite opening 23 is ahot-water chamber 25, that is shaped in crosssection as shown in Fig. 3,and extendsfrom the lower portion of leg 12 upward to the chamber 17.Said water-chamber 25 conforms in outline to the ICO shape ofthedivision-section, but has no water communication therewith.

The reference-number 26 denotes a boss formed on top of the chamber 17,which boss is bored and threaded to receive one of the outlet-pipes ofmy heater, as hereinafter fully described. The said division-section isprovided with a lower portion 22, conforming in shape to the ash-pit ofthe heater, and the wall 22 extends downward into said lower portion toa point in line with or below the chambers 16 of the companion sectionsof the heater.

The wall 22 in said lower portion is provided with a boss 16",corresponding in shape to the chambers 16, and a bar 16 bridges thespace between the walls 22 at the proper point to be bored to receivethe bolt already referred to, by means of which the several sections areheld together. Bosses 27 are provided on the opposite sides of thedivision-section to reoeive certain pipes, as hereinafter described. Thelower part of the division section is formed merely as a thin web 28 todivide the ash-pits of the two minor heaters.

Reference numbers 29 denote cupped bosses formed on wall 22 to receivethe rear ends of the grate-bars.

It is well understood by those conversant with the manufacture of thisclass of heaters that the various sections are usually cast in a singlepiece. This is true of the sections of the herein-described heater, andit will be understood from the foregoing description and from thedrawings that the Water in each section, while having free coursethroughout that section,is,at the same time,not confined therein, buthas communication with adjoining sections through theconnecting-chambers 16 and 17.

In the process of assembling my heater a number of intermediate sectionsare placed on each side the division-section, the number of suchsections on one side exceeding those on the other, and one of the frontsections is then placed at each end of the structure, thus providing thetwo minor heaters of difierent capacity. The said end and intermediatesections rest upon ash-pits and 31, provided for the separate use ofsaid minor heaters, and to tie the several sections togetherarod 33 ispassed through the holes 16 near the bottom of eachsection of thecomplete structure, and a similar rod is passed through the holes l7near the top of each of said sections. The opposite ends of the rods 33are threaded to receive nuts 34, by means of which the several sectionsare forced into and retained in close contact with each other, it beingof course understood that suitable packing may be employed between thesections to insure tight joints. The chambers 16 of each section arebored, as at 16, as shown in the drawings, Figs. 1, 4, 5, 6, 7, 9, and12, to receive the shouldered ends of nipples 35, and the chambers 17are similarly boredto receive nipples 36. Said nipples 35 and 36 areplaced in position when assembling the heater and when the severalsections are forced into close contact provide connections between theseveral sections thatpermit the water therein to pass freely from onesection to the next adjoining one.

The reference-numbers 37 and 38 denote outlet-pipes leading from thechambers 17 at the opposite ends of the structure, and 39 denotes asimilar pipe leading from the boss 26 of the division-section, the saidpipes 37 38,

and 39 conveying water from the heater to radiators or for other uses. H

Inlet or return pipes for my heater are denoted by reference-numbers 40,which pipes enter the division-section at the bosses 27.

The grate-bars of my heater are denoted by reference-number 41. Thesebars have formed thereon the grate-segments 42 and are supported atvarious points by the bearings 18, formed in the Web 18 of eachintermediate section. The upper edge of said webs conforms in outline tothe shape of the gratesegments 42, as will be understood by reference tothe dotted lines in Fig. 6, and at the points Where the bars :41 areengaged by the hearings in said webs the segment 42 is omitted and itsplace is filled by said web. (See Fig. 2.) The inner end of eachgratebar engages and revolves in one of the cupped bosses 29, and theouter end passes through and is supported by a plate 43, secured to thefront sections of the heater. The extreme outer ends of bars 41 aretriangular, as shown, to receive the usual handle or wrench for rockingthe same.

Reference-numbers 44and 45. denote, respectively, the fire-pot orfeed-door and the door through whichthe interior of the upper portion ofthe furnace may be reached.

Number 46 denotes a collar that encircles the opening 23 of thedivision-section and is adapted to receive the smoke pipe 47, as shownin Fig. 3.

- It will now be seen,by reference particularly to Figs. 1 and 3 of thedrawings, that when the several sections are clamped together, asdescribed, the depressions 14 of all confronting sections will coincideand thus provide draftflues leading upward from the fire-pot around theWall lOof the circular openings 13, and it will also be seen that theconfronting depressions l4 will likewise register, thus permit.- ting afree passage of the products ofcombustion from the fire-pot to a pointabove opening 13 and thence downward into and throughsaid opening, asindicated by arrows in thedrawings. Said products of combustion travelthrough openings 13 until deflector-plates 24 24 are reached, whichlatter serve to turn the current of said products into the opening 23and finally outward through the smoke-pipe 47. The depressions 14,confronting the opening 23 of the division-section, are stopped up bymeans of plates 48, as

shown in Fig. 3, and thus the direct passage from the firepot to saidopening is prevented.

The'described current of the caloric products ofcombustion utilizes tothe fullest extent snch products, and the construction of the variousheater-sections presen ts the water to such products in the mostadvantageous manner. It will thus be seen by reference to the drawingsthat the products of combustion serve not only to heat the water whenpassing upward to the openings 13, but also when traveling through saidopenings influence the water within the-waterways 15, crossing saidopenings.- I

In Fig. l is shown a device by means of which the fire is automaticallycontrolled. This is accomplished by a pipe 49, leading upward from thelower end of chamber 25 to a diaphragm in case 50, supported midway thelength of the heater and near the upper portion thereof. Two levers 51are supported in standards 52 on said diaphragm-case, and the longerends thereof are connected by means of chains 51' to the ash-pit doors30 31. The inner ends of said levers are secured to averticalrod 54,controlled by the diaphragm. As the temperature of the water in chamber25 is varied by reason of the influence of the changed temperature ofthe water in the division-section, the diaphragm is correspondinglyinfluenced to move the rod 54 to rock levers 5l,the movement of whichlatter causes the chains 51 to open or close the ash-pit tomatically.

It will now be understood that I provide practically three heatersin asimple structure-that is to say, I provide two heaters of differentcapacities that may be operated in dependently of each other, or theymay be used together to providea heater of the capacity of the two minorheaters.

It will now be obvious that either of the two minor heaters could bemanufactured and used as a complete structure and separate from itscompanion, in which case the rear section Would be substantially likethe division-section here illustrated in Fig. 9, the only materialdifference being in the fact that the opening 13 would be circular, asin the front and intermediate sections, the smoke-pipe being then fittedto the rear of said opening.

Having thus described my invention, I claim- 1. In combination,inasinglestructure,t-wo heaters of different capacities adapted for eitherindependent or conjoint use, said structure embodying an interposedwater-section that serves as the rear section of both of said heaters. I

2. Inasinglestructure,in combination.two heaters, set back to back, andan interposed rear water-section common to both of said heaters, saidinterposed section being formed with a smoke-exit and an angulardeflectorplate 24 24:, substantially as and for the purpose specified.
